Influence of stocking density and temperature on the growth and survival of seahorse juveniles, Hippocampus barbouri (Jordan and Richardson, 1908)
Bibliographic record
Abstract
Low survival of newborn seahorses hindered studies on the early life stage. Many important aspects contributing to the survival of newborn seahorses remained unknown. More research on juvenile stage is necessary to optimize the culture protocols. Stocking density may or may not affect fish growth and behavior. Effect of stocking density on the growth and survival of seahorses in the early stages had received much less attention. Temperature is decisive in the early development of fish, with great impact on primary and secondary production and consequently on growth, survival and feeding of juveniles. It affects metabolism rate of organisms which can greatly impact the growth and survival of seahorse particularly at juveniles’ stage. Hence, effects of stocking density and temperature on the growth and survival of Hippocampus barbouri juveniles were studied. Three treatments of 0.3, 0.4 and 0.5 juv/L, respectively 6, 8, and 10 seahorse juveniles per tank, were tested for 12 weeks. Three temperature levels selected for this experiment were 25, 28 and 31°C for 4 weeks of experimental period. There was no significant different (p>0.05) on the growth of H. barbouri juveniles cultured under different stocking density. This may be due to the stocking densities employed in this study has not reached it maximum limit, hence no significance difference between treatments. Highest survival of 90% was recorded at highest stocking density of 10 juv/tank. Temperature between 25 and 28°C showed better growth of H. barbouri juveniles when compared to high temperature of 31°C. Survival of H. barbouri juveniles cultured under different temperature resulted in more than 80% for all treatments. These findings indicated that H. barbouri juveniles can withstand temperature between 25 and 31°C. To conclude, stocking density of 0.5 juv/L produced the best survival while at temperature between 25 and 28 °C produce better growth and survival of H. barbouri.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
